Yield:75318-43-3 85%

Reaction Conditions:

with disulfur dichloride in dichloromethane at 20; for 18 h;

Steps:



Disulfur dichloride (10 mL, 158 mmol) was added to a solution of 2- chloroacetonitrile (4.0 mL, 64 mmol) in CH2Cl2 (13 mL) at room temperature under an inert atmosphere of argon. The resulting mixture was stirred at room temperature for 18 h. The precipitate was collected by filtration, washed with CH2Cl2 copiously, and then dried to afford 4,5-dichloro-l ,2,3-dithiazol-l-ium chloride (1 1.1 g, yield: 85%). MS (ESI) calcd for C2Cl3NS2 (m/z): 208.52, found: 248.0 [M+K]+, 206.8 [M-2]
